Abstract

The embodiment of the invention provides a wireless data transmission method and system. The method comprises the following steps: detecting a current service type and a data packet sent by a currentservice; and if it is detected that the current service type is a precise control service and a data packet sent by the current service does not need to be segmented, performing wireless data transmission by adopting a rapid submission mechanism, scheduling an RLC layer and an MAC layer in the same task in the rapid submission mechanism, and directly submitting the data packet processed by the RLClayer to an application layer. According to the wireless data transmission method and the wireless data transmission system provided by the embodiment of the invention, a protocol stack is simplifiedaiming at a precise control service demand, and the protocol stack is submitted to an application layer directly by adopting a rapid submission mechanism, so that the transmission time delay caused by serial transmission to a PDCP layer after an RLC layer reorganizes a data packet is eliminated.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless data transmission method and system. Background technique [0002] With the application of new technologies such as LTE-G, the existing precise load control service, referred to as precision control service and equipment deployment in the electric power wireless private network will become a trend. At present, the cost of terminals in the industry is low and the terminal processing capacity is limited. The precise control business of the power industry requires transmission delay <= 50ms, and the packet loss rate of data should be less than 1 / 10,000. These constraints have put forward restrictions on LTE-G network performance. Extremely demanding. [0003] In the current power wireless private network protocol stack, the scheduling of the media access control (Media Access Control, MAC) layer and the radio link control (Radio Link Control, RLC) layer belongs...
